RANGE.

Patented Dec. 22, 1914.

Application filed April 21, 1914. Serial No. 833,412.

To all 2071 am it may concern Be it known that I, Janus F. STArLn'roN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Ranges, of which the following is a specification.

This invention relates to a range and particularly to means for distributing the heat through same.

It is one of the objects of the present invention to provide a simple, substantial and cheaply manufactured range in which the dampers are constructed and arranged in a new and novel manner so as to permit a more perfect control and eiiicient distribution of the heat throughout the range.

Another object is to provide an adjustable flue strip in the bottom of the range by which the heat may be evenly distributed under the oven.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanydrawings, in which Figure 1 is a central Vertical section through the range. Fig. 2 is a plan view of same partly broken away. Fig. 3 is a plan section on line mx, Fig. 1.

Referring to the drawings, A indicates the top plate of the range, 2, 3, 4c and 5 the side and end walls respectively, B the oven,

6 the fire chamber, 7 the upper horizontal fine, 8 the rear down-take flue, 9 the lower horizontal flue, and 10 the main outlet flue which connects with the smoke stack in the renal manner.

The main novelty of the invention consists in the arrangement and construction of the dampers and the adjustable form of flue strip which is provided for the purpose of more evenly distributing the heat throughout the range. The range is in this instance provided with a suitable type of burner, indicated at 11, and the upper horizontal flue, together with the lower horizontal flue, is provided with flue openings 12 and 13 which are arranged in the usual manner; the opening 12 being controlled by the usual form of direct draft damper indicated at 14.

Suitably mounted and extending across ,7 the rear end of the upper horizontal flue is a roll bafiie damper 15 which may be closed,

as indicated in Fig. 1, through means of a handle 16 to prevent the heat from passing down through the down-take flue. Secured in an angular position and extending part way across the lower horizontal flue is a stationary baffle strip 17, and slidably mounted with relation to same is an adjustable flue strip 18, the position of which is controlled by a rod 19 secured thereto which extends through bearing 19 fixed to the side wall of the range and which is provided with a'handle 20 on its outer end. The stationary flue strip is slotted, as indicated at 21, and pins 22secured in the adjustable strip extend through said slots, said pins being headed on their outer ends to prevent the strips from coming apart and at the same time permitting strip 18 to be moved in or out with relation to the stationary strip.

in operation, if it is desired to concentrate he heat under the top plate of the range, it is accomplished by closing the bafiie damper 15, as indicated in Fig. 1, and opening the direct ramper lat. Heat from the burner is thus directed under the top plate and is then permitted to escape through the opening 12 into the main outlet flue 10. If it is desired to use the oven for baking purposes it be comes necessary to close the direct damper 1i and open damper 15. This permits the heat from the burner to pass through the upper horizontal flue down the rear downtake flue and through the lower horizontal flue where the heat is permitted to escape through the opening 18 into the main outlet line. The position of the adjustable flue strip permits the heat entering through the rear down-take flue to be evenly distributed under the bottom of the oven, as indicated by arrows a in Fig. 3; the desired distribution of heat being secured by sliding the adjustable strip 18 in or out with relation to the stationary strip. A perfect distribution may not only be obtained in this manner,

but the volume of heat or draft passing therethrough may be increased more or less by moving the strip in or out.

A range constructed as here shown is simple and substantial in construction, and the arrangement and construction of the dampers and flue strip permit a much more efficient control and distribution of heat than has heretofore been obtained in similar ranges. A better result can thus be obtained. The materials and finish of the several parts of the range are such as the experience and judgment of the inahufacf turer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within ,the scope of the appended claim and that I do not wish to limit myself to the specific design and construction here shown.

' Having thus described my invention, what I claim and desire to secure by Letters Patent is i A range of the class described comprising a body having an oven mounted therein, flues disposed above and below the oven, a downgtake flue aiiording communicationbetvreen'said fiues, a bafile strip having an angularly disposed end rigidly connected to one side wall of the body, whereby said str ip is disposed diagonally within the lower flue, the free end of said strip being spaced from the opposite side wall, said strip having'its upper and lower longitudinal edges resting flush against the bottombf the oven and witnesses.

body, respectively, said strip having a longitudinal slot formed therein, a secondary strip provided with pins for slidably engaging said slot and having its upper and lower edges slidably engaged With the bottom of the oven and bottom of the body, a longitudinal bearing mounted upon one side of the body, a rod slidably engaged in said bearing and having its inner end rigidly secured to one end of the secondary strip, the outer end of said rod being located exteriorly of the body, andserving to enable adjustment ofthe secondary strip to partially or totally close the space between the free end of the baffle strip and adjacent side of the body, whereby the flow of heat from the down-take flue may be regulated in its pas sage under the oven.

in testimony whereof I have hereunto set A ,7 my hand in the presence of two subscriblng JAMES F. STAPLETON. Witnesses JOHN- H. HERRING,
